The ones digit of a 2-digit number is twice the tens digit. When the number
formed by reversing the digits is added to the original number, the sum is 99. Find
the original number.

Answer 1

Answer:

Let the tens digits =x

so, ones digits = 2x

number= 10x+2x=12x

reverse number= 10{2x}+x=20x+x=21x

it is given that

12x+21x=99

or 33x= 99

so,x=3

original number =10x+2x

30+6
